KTP 10106664: Knowledge transfer partnership between University of Strathclyde and ETHER NDE LIMITED

Mohseni, Ehsan (Principal Investigator) Dobie, Gordon (Principal Investigator) MacLeod, Charles Norman (Principal Investigator)

ETher NDE has identified a significant potential market for in-process Non-Destructive inspection, of high temperature additive manufacturing.
In most traditional material manufacture, inspection is done on a finished soliditem after manufacture. Whereas in additive manufacture, there is the opportunityfor inspection as the layers are built up. This would be particularly relevant forparts where the core is an open lattice (for reasons of weight reduction), whichmakes conventional non-destructive testing (NDT) at the best very difficult and atworst impossible.
It is imperative that the new product offering is integrated seamlessly with ETherNDE's existing technology where complementary hardware and applicationrequirements align. The innovative proposed product will be designed to work withexisting Eddy Current hardware from ETher's product range. There'll be a PCapplication to facilitate data collection, display, analysis, and reporting.
The metal additive manufacturing market is still emerging, and engagement withAM machine builders has revealed a significant gap in NDT technology. ETherNDE is ready and well-positioned to enter the Eddy Current array market for metalAM in aerospace, and other sectors, with the vision and ambition of overtakingtraditional in-process inspection, thereby helping them gain a technological edgeover their global competitors.

KTP 10106861: Knowledge transfer partnership between University of Strathclyde and NATIONAL OILWELL VARCO UK LIMITED

Mohseni, Ehsan (Principal Investigator) MacLeod, Charles Norman (Principal Investigator) Lines, David (Principal Investigator)

The National Oilwell Varco UK Limited team in Forfar is responsible for the standardisation of non-destructive evaluation (NDE)procedures for our equipment across the globe. Conventional calibration practicedby NOV can be unreliable, as the testing equipment may travel thousands of milesoverseas after the initial calibration. The rigours of the journey could can alter thecharacteristics of the calibration equipment and thus make comparison toequipment in the field unreliable. NOV's oilwell drilling components are oftenmetres in span and extremely heavy, which makes it practically impossible to havestandard reference blocks of the same size as the original equipment. Introducingportable, down-scaled sensitivity pieces for calibration use in the field willtransform the reliability of NDE processes and safety of the components inoperation, minimising the risks of failure and shutdown. The accuracy of amanufactured sensitivity piece is critical: the defects/discontinuities must bereliable and consistent with the piece of equipment targeted for calibration.
Through this KTP, NOV will gain the permanent capacity to design, manufacture,and use sensitivity pieces for in-field inspection of equipment using Phased ArrayUltrasonic Testing (PAUT).

Multi-Modal Sensing for Heavy-Manufacturing Robotic Welding

Loukas, Charalampos (Principal Investigator) MacLeod, Charles Norman (Principal Investigator)

Fusion welding of metals is a joining method fundamental to High-Value Manufacturing (HVM). Distinctive challenges such as the global shortage of welders and the increasing requirement for high-integrity components in the energy and defence sectors fuel the need to research and adopt digital welding
technologies such as sensor-enabled robotic welding. Surface and volumetric sensing approaches at the point of manufacture coupled with real-time robotic motion offer the possibility to control, adapt and consistently ensure defect-free fusion. This project seeks to investigate novel event-based neuromorphic vision sensing coupled to high-temperature in-process ultrasonic imaging to deliver high-integrity welds right the first time.
